(NATIONAL) – The parents of two children who died in the Sandy Hook school gun massacre in 2012 have filed defamation lawsuits against “Infowars” show founder and well known right-wing conspiracy theorist Alex Jones over Jones’ alleged false claims that the mass murders at the school by a lone gunman were a “staged” event.

The Huffington Post reported that lawyers for the parents say Jones’ conspiracy theories—including the false assertion that the parents of dead children are “crisis actors”—have led to death threats against them.

Neil Heslin, the father of a 6-year-old boy killed in the shooting, and Leonard Pozner and Veronique De La Rosa, who also lost their son, filed the suits late Monday, the Huffington Post reported.

Each action seeks $1 million in damages from Jones, Infowars and a related company, Free Speech Systems LLC. The Post reported that Mark Bankston, the lawyer handling the cases for the parents told a Post reporter, “Even after these folks had to experience this trauma, for the next five years they were tormented by Alex Jones with vicious lies about them and these lies were meant to convince his audience that the Sandy Hook parents are frauds and have perpetrated a sinister lie on the American people.”

Bankston is also involved in another defamation suit against Jones, that one representing a man whom Jones allegedly incorrectly identified as the Parkland, Florida school shooter who murdered 17 people at Marjory Stoneman Douglas High School in February.

And in March, the man who recorded on video the deadly car attack at last year’s white supremacist rally in Charlottesville, Virginia, filed a lawsuit against Jones for calling him a “deep state shill” and a “CIA asset” who helped organize the attack.

The man claims he is not a deep state “shill” or a CIA “asset” and that he did not help organize the attack.
